Blackford, who is due back in court March 27, remains on desk duty as a result of the Allied Gardens crash.

The detective faces two misdemeanor counts of driving under the influence and a special allegation of reckless speeding at the time of the accident.

He faces between four days and six months in jail and standard fines if convicted. The enhancement carries 60 days in jail above any other penalty, even if he is granted probation, Coburn said.

San Diego police acknowledged the Dec. 7 accident on Dec. 13, after U-T Watchdog asked about it. A department spokeswoman first said the crash was reported at 2:05 a.m.

After the Watchdog obtained a security video that showed the time to be 12:56 a.m., the spokeswoman said there was a delay in entering the event into the dispatch system.

The City Attorney’s Office went to court earlier this month to force police officials to provide information about the accident, including results of an initial blood-alcohol screening for purposes of an internal investigation.

Court records say numerous officers were at the scene shortly after the crash even though a traffic investigation was not opened for more than two hours.

Investigators waited over three hours to administrer a breath test for the official DUI investigation, court records show.

When Blackford “finally” was tested, as the City Attorney’s Office put it in court records, he recorded a blood-alcohol content of 0.09 percent, just over the legal limit.

The department has said Blackford was off-duty at the time of the crash, but has not yet responded to the Watchdog’s records request for duty logs and other documents that would show that.
